Special Accessories (Options) 19.1 Below-Balance-Weighing Hook With the below-balance-weighing hook, the sample can be suspended below the balance for weighing. This is particularly useful for specific gravity measurements. Attaching the hook to the balance (1) Turn off the power. (2) Remove the pan and pan supporter. (3) Remove the seal on the back of the balance. (4) CAUTION! While holding down the pan supporter shaft, screw the hook into the screw hole on the bottom of the balance by hand. (Do not use any tools such as a monkey wrench to tighten the hook, as it may damage the sensor inside the balance.) (5) Place the balance at a place where no excess force is applied to the hook. (6) Remount the pan supporter and pan onto the pan supporter shaft.
